[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a universal tying tool capable of freely changing a tying dimension.

[0002]

2. Description of the Related Art Conventionally, as a binding tool composed of this kind of flexible member, a locking projection is generally provided at one end of a belt-shaped main body,
An engaged portion such as an engaging groove and an engaging portion such as an engaging hole and an engaging claw are provided at the other end of the engaging portion to bend the strip-shaped body in a substantially annular shape. Tighten by engaging and fitting with the locking part. In this way, the belt-shaped main body bent in a substantially annular shape is used to bind or tighten the articles. Locks provided at both ends of the so-called strip-shaped body
It has a structure in which the locked means is connected. As prior art documents related to the present invention, there are, for example, a tie of Japanese Utility Model Laid-Open No. 1-82166 and a package such as stockings of Japanese Utility Model Laid-Open No. 61-45371. Incidentally, there is a binding band used in the net binding holding method of Japanese Patent Laid-Open No. 4-189762 as a prior art document having the same configuration as the above and capable of adjusting the binding size in a wide range. This binding band is a synthetic resin integrally molded product in which a large number of slit holes are formed in a thin, long and flexible band at equal pitches, and constricted portions are formed at positions between the slit holes. .

[0003]

Since the prior art is the tightening or releasing of tightening / unlocking means provided at both ends (both ends) of the belt-shaped main body, the minimum or maximum winding size is required. Or, the stepwise size of the winding size is standardized. Therefore, the above-mentioned dimensions cannot be changed, and problems remain in improving versatility and adjusting the strength of the tightening force. Incidentally, JP-A-4
The invention of No. 189762 has the advantage that the minimum or maximum winding size can be adjusted. However, since the stepwise adjustment of the winding size is standardized, there is a problem in fine adjustment such as the strength of the tightening force.

[0004]

SUMMARY OF THE INVENTION In view of the above, the present invention provides
The following configurations are adopted with the intention of making multidimensional adjustments of dimensional changes and more precise adjustment of the tightening force.

In the universal tying member of the present invention, the pair of holding pieces for holding and the space portion for insertion are arranged on one side, and the space portion is inserted on the other side for being locked by the locking piece. A strip-shaped main body each having a stopper, wherein the strip-shaped main body is formed in a substantially annular shape at the time of bundling, and the locking strip is inserted into the space portion and provided on both side surfaces of the locking strip. It is configured to engage the recessed strip with the pair of locking pieces.

[0006]

In the case of binding an article using the universal tying device of the present invention, as a general rule, after the article is wound around with the locking strip on the outside, the locking strip at one end is placed in the space at the other end. insert. At this time, in order to smoothly insert the locking strip into the space or prevent removal after the insertion, a pair (pair) of locking protruding (obliquely installed) from both inner wall surfaces of the space is provided. The piece has a constriction at its base end and a hemispherical surface at its free end. Further, the fact that the locking pieces of this pair are inclined allows the smooth insertion of the locking strips, and then the locking strips are grasped at the inclination angle of the locking pieces of the pair so as to be removed (arrow A). To prevent it from swinging (see Fig. 3). This state (Fig. 3
When the locking strips are inserted into the space, as shown in (1), the pair of locking strips obliquely arranged from the space are press-fitted into the pair of recessed strips provided on the side surface on the compatibility of the locking strips. A buffer space area is formed between the pair of locking pieces and the inner wall surface of the space. This buffer space region has a role of giving elasticity to the flexible tying tool of the present invention and protecting the article when the article is bound. Further, in the case of releasing the article bundling, when the shoulder portion or the exposed locking strip of the strip-shaped main body is gripped and the end portion on the insertion side is pulled, the locking strip is pulled in the pulling direction (B arrow). Be pulled. Along with the movement of the locking strip in the pulling direction, the pair of locking pieces are bent in the direction of the arrow A in a circular motion (see FIG. 3), and finally the initial inclination is almost the same. It is opened in the symmetrical position (Fig. 3).
reference). At this time, the contact pressure between the inner surface side of the hemispherical surfaces of the pair of locking pieces and the outer peripheral curved surfaces of both convex projections of the locking strips (see the state of FIG. 3) helps expand the tensile force required for the detachment. It is composed. That is, the locking strip is disengaged from the pair of locking pieces only when a tensile force exceeding the contact pressure is applied (see the state of FIG. 3).

[0007]

An embodiment of the present invention will be described below.

Reference numeral 1 denotes a locking strip 2 which has a convex strip on the other side 111.
On the one side 112, the recessed space portion 3 and a pair of locking pieces 4, 4 projecting from the inner wall surface 31 of the space portion 3 into the space portion 3.
Seen from the side (viewed from the side)
It is a strip-shaped main body having a substantially inverted T shape, and has an appropriate length in the longitudinal direction (C arrow). Both shoulder surfaces 113 of the strip-shaped main body 1 or the top surface 2b of the locking strip 2 are provided with a large number of recessed strips 5 in the width direction (direction orthogonal to the longitudinal direction) of the strip-shaped main body 1. The purpose is to insert both ends (one end 1a and the other end 1b), to prevent misalignment during binding, to facilitate winding of the belt-shaped main body 1, and the like. The locking ridge 2 has a concave ridge 211 on its compatible upper side surface 2a, and a hemispherical outer peripheral curved surface 212 is formed at the connecting portion of this compatible upper side surface 2a and the top surface 2b.
Have respectively. Further, buffer space regions 411 and 411 are formed between the inner wall surface 31 of the space portion 3 and the pair of locking pieces 4 and 4. In the figure, reference numerals 412 and 412 denote constricted portions of the pair of locking pieces 4 and 4. In the example shown in FIG. 5, the size of the space 3 is reduced, and the strips 6 are provided for the purpose of expanding the gripping force and imparting elasticity to the belt-shaped main body 1. Further, there may be a case where a recessed strip (not shown) is provided on the ceiling inner wall surface 32 of the space 3.

[0009]

As described in detail above, a locking strip is provided on one side of the strip-shaped main body, and a pair of locking pieces engaging with the locking strip and a space portion allowing insertion are provided on the other side. Since they are provided respectively, they have the following effects.

For example, after one end of the strip-shaped body is pressed into the pressing article, it is rolled up once, and the other end is simply placed and pressed on the one end without loosening.

When it is desired to bind the product tightly, it is easy and convenient to carry it by pulling it strongly when placing it on one end. In addition, by repeating this operation and the detaching operation described later, it is possible to reuse again and again, which is useful.

During bundling, the entire shoulder surface of the other side is in close contact with the one side, there is no rebounding portion of the lump, and the entire body fits neatly.

In order to release the binding, the locking strip at one end can be released by pulling it up and can be removed by a simple operation.

Since it can be cut to any length as long as it is necessary, there is no waste and the size can be freely set.

Both ends are free ends, and either end can be used.

There is no specific engagement positional relationship (locking locking portion), the whole shape is the same and smooth, and reliable binding is possible.
